Definitions

  • the present invention relates to a recording and to a video camera.
  • a conventional video camera using a recording tape has the ability of displaying the time of recording (1) and the remaining tape storage space (2) within the viewfinder as shown in Fig. 7A. Since the remaining tape length on the reel cannot be detected accurately, the remaining tape storage space is given in terms of the approximate remaining record time as shown in Fig. 7B. Specifically, display “F30” signifies that the tape remains for recording 30 minutes or more, and display “30-25” signifies that the tape remains of recording 25 to 30 minutes.
  • This video camera is devised to alarm the user of the run-out tape in 2 minutes or less by the blinking display "5-0".
  • the video camera user is obliged to be ready to terminate the shooting by watching the display of remaining tape and the blinking display of tape-end alarm.
  • the tape-end alarm blinks during the shotting of a climax scene, the user must unfortunately halt the shooting and set a new tape cartridge or rewind the recorded tape with the intention of overwriting in case a new tape is not at hand.
  • Embodiments of the present invention seek to provide a disk recording apparatus and a video camera using the same with the intention of allowing the user to extend the available record time easily.
  • An embodiment of a disk recording apparatus is designed such that if the disk storage space runs out during the recording operation, it searches for a record are with its content deemed unwanted and voidable based on the disk and records the successive signal by overwriting in the detected area.
  • An embodiment of a video camera according to the invention is designed such that if the disk storage space runs out during the shooting of a scene, it searches for a record area with its content deemed unwanted and voidable based on the accompanying management information recorded on the disk and records the successive image signal by overwriting in the detected area.
  • a disk recording apparatus and video camera are designed to record signals, e.g., image signals, and management information pertinent to the recorded signals on a disk-type recording medium in such a manner that, if the storage space of the recording disk runs out during the recording operation, a record area with its content deemed unwanted and voidable is detected based on the accompanying management information and the detected are is used to overwrite the successive signal, thereby extending the available record time.
  • signals e.g., image signals
  • management information pertinent to the recorded signals on a disk-type recording medium in such a manner that, if the storage space of the recording disk runs out during the recording operation, a record area with its content deemed unwanted and voidable is detected based on the accompanying management information and the detected are is used to overwrite the successive signal, thereby extending the available record time.
  • a recording apparatus and a video camera are designed to record signals, e.g., image signals, the management information pertinent to the recorded signals on a disk-type recording medium, and during the recording operation in the record time extension mode specified on the operation panel, if the disk storage space runs out, the largest area or the area nearest to the recording head at the run-out of storage space, among the areas with their contents deemed unwanted and voidable searched based on the accompanying management information, is used to record the successive signal by overwriting.
  • FIGS. 1A and 1B show the side view and front view of a video camera based on an embodiment of invention
  • Fig. 2 shows its internal arrangement.
  • the video camera has a lens section 11, which focuses the image of a subject on the imaging plane of an imaging section 12.
  • the imaging section 12 produces an electrical signal from the image, and further produces a image signal DC from the electrical signal.
  • the image signal DC is fed to a signal converter 13, which implements the coding process for the image signal DC to produce a record signal WD, and it is fed to a recording section 14.
  • the image signal DC is also sent to a viewfinder 16.
  • the recording section 14 uses a disk-type recording medium of the MO or phase modulation type optical disk which can be overwritten, and the record signal WD produced by the signal converter 13 is recorded on it.
  • the recording section 14 When the video camera is operated in reproducing mode, the recording section 14 reproduces a record signal on the recording disk to produce a reproduced signal RD, and it is fed to another signal converter 15. The recording section 14 further produces an information signal RM indicative of the remaining record time of the recording disk, and it is sent to the viewfinder 16.
  • the signal converter 15 renders the multiplexing for the reproduced signal RD to produce a reproduced video signal DP, and it is sent to the viewfinder 16.
  • the video camera has an operation panel 18, and an operation signal PC produced in response to the user's operation on the panel is sent to a controller 20.
  • the controller 20 produces a control signal CS from the operation signal PC, and sends the signal CS to the signal converter 13, recording section 14, signal converter 15, and viewfinder 16, thereby controlling these sections.
  • the operation panel 18 includes REC key 18a, TAKE key 18b, NG key 18c, and CONTINUE key 18d.
  • the REC key 18a is pressed to start or halt the recording of the image signal DC.
  • the TAKE key 18b is pressed to record information at In-point and Out-point, which are moments of operation of the key, so that the user can recognize each scene at the later editing task.
  • the NG key 18c is pressed to record information indicative of the shot scene to be a NG scene, i.e., a faulty shot or redundant shot, so that the user can easily avoid such an unwanted scene at the later editing task.
  • the information of In-point, Out-point, NG scene, and time of shooting is stored temporarily in memory means, and it is recorded in the management information area on the innermost track of the recording disk after the recording operation is brought to the standby state or the recording operation is terminated.
  • the information of In-point, Out-point and NG scene maybe recorded in an IC memory which is attached on the cartridge of the recording disk.
  • the viewfinder 16 can display a picture derived from the image signal DC or reproduced video signal DP, and it further displays the remaining record time label 16a, disk near-end alarm label 16b, recording time/time code label 16c, and operating condition labels 16d-16g, as shown in Fig. 3, based on the control signal CS and information signal RM.
  • the recording operation label 16d is displayed.
  • the TAKE label 16e is displayed.
  • the NG key 18c is pressed to mark the shot scene to be voidable, the NG label 16g is displayed.
  • the video camera begins to record the image signal on a track of the recording disk 30 shown in Fig. 5.
  • the TAKE key 18b is pressed
  • the In-point information and Out-point information are generated so that the user can recognize scene 1, scene 2, scene 3, and so on. If the user presses the NG key 18c following the shooting of the scene 3, information indicative of voidableness is generated for it.
  • the In-point and Out-point information and voidance approval information are stored temporarily in the memory.
  • the user can known from the information "A" recorded in the management information area 31 that the image signal of the intended scene 1 is recorded from starting address a, known from the information "B” that the image signal of the scene 2 is recorded from starting address b, and known from the information "C” that the image signal of the voidable scene 3 is recorded from starting address c.
  • the user will want to shoot a scene continuously beyond the expected remaining record time even in the presence of a blinking display of remaining record time label 16a and a display of near-end alarm label 16b in the viewfinder 16.
  • the user presses the CONTINUE key 18d to extend the available record time.
  • the CONTINUE key 18d is pressed, the CONTINUE label 16f indicative of record time extension and another label 16h of the extended remaining record time as a result of a record time extension process are displayed as shown in Fig. 3. Consequently, the user can be notified of the extended time length for shooting by the extended remaining record time label 16h.
  • step ST1 causes the display of remaining record time label 16a to blink on each expiration of one second and displays the disk near-end alarm label 16b in the viewfinder 16.
  • Step ST2 detects as to whether or not the CONTINUE key 18d is pressed by the user for record time extension.
  • the control sequence proceeds to step ST3 in response to the operation of the CONTINUE key 18d, or otherwise proceeds to step ST5.
  • Step ST3 displays the CONTINUE label 16f in the viewfinder 16.
  • This label is displayed in the form of blink, changed color, monochrome inversion, shading, or a combination thereof, so that the user can easily confirm the record time extension in effect.
  • the recording disk is searched for areas where image signals of NG scenes are recorded based on the information recorded in the management information area, and record times of these NG scenes are summed.
  • the summed record time of NG scenes is added to the remaining record time to evaluate the extended remaining record time, and it is displayed as the extended remaining record time label 16h.
  • the control sequence proceeds to step ST4.
  • the controller 20 moves the recording head from the position of image signal of the current scene to an area of image signal of an NG scene based on the information recorded in the management information area.
  • the image signal of the current scene is recorded continuously by overwriting in the NG scene area.
  • the controller 20 moves the recording head to the area of the longest NG scene so as to provide the longest extended record time in one NG scene area, or alternatively moves the recording head to the nearest NG scene area so that it uses the smallest space of the buffer memory which holds the image signal temporarily at the transition of head position.
  • Displaying both the remaining record time label 16a and extended remaining record time label 16h allows the user to recognize easily the expected record time extension and also the timing of switching to a NG scene area after the remaining record time will run out. The user can stop the blinking of the remaining record time label 16a so as to read the displayed value easily and remove the redundant sign.
  • the remaining record time label 16a and extended remaining record time label 16h are displayed selectively by being switched, in which case the user can watch more easily the viewfinder having fewer displayed items.
  • step ST5 examines the value of remaining record time. If the remaining record time is still non-zero, the control sequence returns to step ST2 for the detection of record time extension mode. Otherwise, if the remaining record time becomes zero, the control sequence proceeds to step ST6 to terminate the recording of image signal.
  • a new image signal is recorded by overwriting on the image signal of a NG scene
  • information of NG scene overwritten and recorded is held in the memory together with the record position pertinent to the recorded scene and recorded in the management information area on the innermost track of the recording disk on completion of recording or at the halt of recording (standby state).
  • a successive image signal may be recorded by overwriting in the area of the next-longest NG scene or in the area of a NG scene nearest to the overwritten area.
  • the user presses the CONTINUE key 18d during the shooting in expectation of the run-out of record time, and when the value of remaining record time of the recording disk other than the record position of NG scene becomes zero, the image signal is recorded continuously in the manner of record time extension by overwriting in an area of voidable record, e.g., the largest area of voidable record or the area of voidable record nearest to the current recording position.
  • an area of voidable record e.g., the largest area of voidable record or the area of voidable record nearest to the current recording position.
  • Signals recorded on the recording disk are not confined to image signals, but audio signals and other data signals can also be recorded on it obviously.
  • the record time extension when the record time extension is specified on the operation panel during the recording operation for a signal, and when the remaining record time of the recording disk is running out, it is possible for the user to record the signal continuously in the manner of record time extension by overwriting in an area of voidable record, e.g., the largest area of voidable record or the area of voidable record nearest to the current recording position, based on the management information of recorded signals.
  • an area of voidable record e.g., the largest area of voidable record or the area of voidable record nearest to the current recording position
